Fungus around a Indian bean tree.

[Scottie]

The photos below come from Harlow Carr RHS garden in Harrogate and the tree is an Indian Bean Tree (Catalpa bignonioides). Over this summer they had some one in to airspade the roots to break up decompaction.

 

I think the fungus could be Pholioto squarrosa. Am I right? Sorry for the poor quality of the pictures as I took them with my Blackberry.

I would think this is pholiotta squarosus, a root rot of the white persuasion, rain has washed off many of the velum scales but the stipes should still be a little "furry"

From the prolific (panic) fruiting (triggered by airspading) of this biotrophic parasite, one can derive the trunk base and buttresses probably will be decayed (simultaneous white rot) to a great extend, making the tree vulnerable for windthrow by a storm "hitting" on the tree on the affected side.

Thanks yet again Hamadryad. Not good then, especially if it is in such a prominent garden such as Harlow Carr. Would you have any idea if the fungus could be controlled to give the tree a chance of surviving? It is an amazing speciemen.

The pholiotta squarosus was all the way round the bas of the tree.

Pholiota squarrosa was all the way round the base of the tree.

 

Panic fruiting because of decomposing the base of the tree, the buttresses and (part of) the root plate making the tree even more vulnerable for windthrow.

You guys know me well enough to know i dont like felling options.

 

whoever did the airspading should have picked up on decay, checking while the root crown is exposed is common sense.

Who said they didn't ?

 

Maybe there is an ongoing program in place that includes reduction ?

 

Can't hypothesise without the facts.

 

 

 

 

 

btw, I can't see the photos.

 

Best be safe eh, get it felled !
